- * USB Wacom Graphire and Wacom Intuos tablet support
- *
- * Sponsored by SuSE
- *
- * ChangeLog:
- * v0.1 (vp) - Initial release
- * v0.2 (aba) - Support for all buttons / combinations
- * v0.3 (vp) - Support for Intuos added
- * v0.4 (sm) - Support for more Intuos models, menustrip
- * relative mode, proximity.
- * v0.5 (vp) - Big cleanup, nifty features removed,
- * they belong in userspace
- * v1.8 (vp) - Submit URB only when operating, moved to CVS,
- * use input_report_key instead of report_btn and
- * other cleanups
- * v1.11 (vp) - Add URB ->dev setting for new kernels
- * v1.11 (jb) - Add support for the 4D Mouse & Lens
- * v1.12 (de) - Add support for two more inking pen IDs
- * v1.14 (vp) - Use new USB device id probing scheme.
- * Fix Wacom Graphire mouse wheel
- * v1.18 (vp) - Fix mouse wheel direction
- * Make mouse relative
- * v1.20 (fl) - Report tool id for Intuos devices
- * - Multi tools support
- * - Corrected Intuos protocol decoding (airbrush, 4D mouse, lens cursor...)
- * - Add PL models support
- * - Fix Wacom Graphire mouse wheel again
- * v1.21 (vp) - Removed protocol descriptions
- * - Added MISC_SERIAL for tool serial numbers
- * (gb) - Identify version on module load.
